Ever wondered what the Aurora Borealis really look like?

Here she is filmed in realtime. This is not a time lapse and she really like like that.

Victory awaits the one, that has everything in order - luck we call it
Defeat is an absolute consequense for the one that have neglected to do the necessary preparations - bad luck we call it

There is all kinds of colors in the Aurora. Depends on what gasses in the atmosphere it hits. The aurora is caused by charged particles in the solar wind colliding with atmospheric atoms and ions. The collisions cause the electrons of the atmospheric atoms to become excited. As the electrons return to their original energy levels, these atoms emit visible light of distinct wavelengths, to create the colors of the display we see.
The color of the aurora depends on the wavelength of the light emitted. This is determined by the specific atmospheric gas and its electrical state, and the energy of the particle that hits the atmospheric gas. The atmosphere consists mainly of nitrogen and oxygen, which emit the characteristic colors of their respective line spectra. Atomic oxygen is responsible for the two main colors of green (wavelength of 557.7 nm) and red (630.0 nm). Nitrogen causes blue and deep red hues. http://www.webexhibits.org/causesofcolor/4D.html
